What is the main difference between long-term adolescent changes and immediate hand withdrawal?
Answer and explanation
Correct answer: The first is a slow hormone-based effect and the second is a fast nerve-based effect
Adolescent changes such as growth of body hair and maturation of reproductive organs develop gradually because hormones travel through the blood and act comparatively slowly. In contrast, withdrawing the hand from a harmful stimulus is a rapid nervous response, usually organised through a reflex arc involving the spinal cord. Hence A correctly contrasts endocrine coordination with nervous coordination; the other statements reverse or misidentify the processes.
